我们通过实验比较了传统单模光纤(SMF)和三种不同的光子晶体光纤(PCF)的光学带宽，这些光纤都是为可见光应用而优化的。测量了光谱衰减、单圈弯曲损耗和模场直径(MFD)，发现对于相同的模场直径，PCF具有比SMF大得多的带宽。说明了如何利用这一优势来实现PCF更大的MFD，同时保持抗弯曲光纤。
We experimentally compare the optical bandwidth of a conventional single-mode fiber (SMF) with 3 different photonic crystal fibers (PCF) all optimized for visible applications. The spectral attenuation, single-turn bend loss, and mode-field diameters (MFD) are measured and the PCF is found to have a significantly larger bandwidth than the SMF for an identical MFD. It is shown how this advantage can be utilized for realizing a larger MFD for the PCF while maintaining a bending resistant fiber.
